Jae 21 WEEK WITNESS S ATTORNEY NW v SIDNEY WILLIAMS, 0F ELK MOUNTAIN, OBKING.

WRENCH.

Application filed January a, 1917. Serial No. iconic.

To all whom it may concern:

Be it known that I, S nner WILLIAMS, a citizen of the United States, residing at Elk Mountain, in the county of Carbon and State of Wyoming, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.

This invention relates to an improved wrench and the principal object of the invention is to provide a wrench of the ratchet type having an improved type of movably mounted jaw carrying plates and to further provide an improved type of pawl for enga ing the ratchet teeth of the plate.

' nother object of the invention is to provide an improved type of stationary and movable jaw carried by the jaw carrying plate.

Another object of the invention is to provide an improved type of handle having provision made therein for pivotally mounting the pawl.

This invention is illustrated in the accompanying drawings, wherein Figure 1 is a plan view of the wrench looking from one side with the cover plate of the pawl broken away.

Fig. 2 is a plan view looking at the oppogite face of the wrenchfrom that shown in Fig. 3 is a view showing the wrench in side elevation.

Fig. 4 is a longitudinal sectional view through the wrench.

lhe head 10 of this wrench is provided with a handle 11, the handle being provided with an enlargement having a cutout formed therein to provide a pocket 12in which there is pivotally mounted the pawl 13 the finger 14 of which engages the ratchet teeth 15 of the plate 16. The spring 17 which is U- shaped and mounted upon the pin 18 engages the pawl thus yieldably holding the same in the position shown in Fig. 1 with its tooth engaging the ratchet teeth as previously stated. A cover plate19 is secured by means of rivets 20 and serves to protect the spring and pawl. Upon each side of the plate there is provided a stationary jaw 21- which is positioned about the openlng 22 in the plate 16 and is provided with a passageway in which is slidably mounted, the shank of a movable jaw 23, the shank forming a rack 24 engaged by the worm screw 25 mounted in the pocket 26. By turning these adjusting screws 25, the movable jaws may able and stationary jaws. When the wrench is in place, the handle may be grasped and by moving it with an oscillating movement, the finger 14 of the pawl will engage the teeth'of the plate 16 thus rotating the plate in a step by step movement and either tightening the nut or loosening-the same accordingto the position in which the wrench is placed.

1 have thus provided a wrench which will be very convenient to handle and which will be strong and durable and comprises a comparatively few number of parts.

What is claimed is 1. A. wrench comprising a handle formed at one end with a ring shaped head, a plate rotatable within said head and provided with a nut receiving opening, means carried by said handle to rotate said plate, casings formed on opposite sides of said plate in proximity to said openings, stationary jaws formed integral with said casings, sliding jaws cotiperating with said stationary jaws, and provided with shanks, said shanks being slidably disposed in said casings, and

adjusting means engageable with said shank to move the sliding jaws relative to the stationary jaws.

2. A wrench including a handle provided with a head, a plate rotate-idly carried by the head and provided with an opening, means carried by the handle for turning the plate, stationary jaws mounted upon opposite sides of the plate and positioned in operative relation to the opening of the plate, movable jaws each including a shank slidably carried by a stationary jaw and forming a rack bar, and adjusting screws rotatably carried by the movable jaws and engaging the teeth of the rack bar.

In testimony whereof I ai'iix my signature in presence of two witnesses.

SIDNEY WILLIAMS.
